Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a railroad crossing fence to be installed on both sides of a railroad crossing where a railroad track and a road intersect.

[0002]

[Prior art]

 Conventionally, railroad crossing caution fences have been installed on both sides of the entrance and exit of the railroad crossing in order to recognize the existence of the railroad crossing. In general, this railroad crossing caution fence consists of concrete, aluminum, and wooden moon-shaped fences, which are finished in a yellow and black tiger stripe pattern and have many retroreflective plates attached to the top. there were.

[0003]

[Problems to be solved by the device]

 However, when driving at night, the retroreflective plate reflects the light emitted from the headlights of automobiles and makes it visible to the driver, but the intensity of the reflected light varies depending on the mounting angle and the irradiation angle of the headlights. Also, since the irradiation light that reaches the retroreflector from a distance is weak, the function of the retroreflector is not fully exerted, and therefore it is difficult to recognize the existence of a railroad crossing from a distance, and the recognition of the existence of a railroad crossing is delayed. There was a problem that it would end up. Furthermore, although the level crossings where automobiles pass are illuminated, it is dark, but small suburban level crossings are dark and dark, so it is very difficult for pedestrians and cyclists to recognize the presence of level crossings. It was dangerous.

In view of the above situation, the present invention enables a driver of a vehicle, a pedestrian, and the like to surely and visually check the vehicle all day long even when the road condition is bad, and to surely check it from a distance at night. The purpose is to provide a railroad crossing caution fence that can contribute to the safety of vehicles and trains.

[0005]

[Means for Solving the Problems] A means for solving the above problems according to the present invention is to provide a cutout portion in a fence and provide a self-luminous device for lighting a light emitting diode in a solar cell module in the cutout portion. In this self-luminous device, a solar battery module is connected to a storage battery, a switch, and a lighting circuit interposing an electronic circuit for controlling the blinking of a light emitting diode, and a predetermined voltage of its electromotive force is applied to the solar battery module. It is characterized in that a sensor circuit for detecting and closing the switch at a predetermined voltage or lower and outputting a signal opening at a predetermined voltage or higher is connected.

[0006]

[Action]

 The railroad crossing fence according to the present invention detects the predetermined voltage of the electromotive force of the solar cell module with a sensor circuit built in the self-luminous device, and when the electromotive force is brighter than the predetermined voltage during the daytime, the electromotive force of the solar cell module is detected. When the electromotive force is charged to the storage battery and the electromotive force is below the specified voltage in the dark, such as at night, the lighting circuit is activated and the light emitting diode blinks.Since it self-luminesce, passersby can be sure to confirm from a distance. become.

[0007]

【Example】

 The railroad crossing caution fence according to the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the fence 1 is formed in a moon-shape with a non-corrosive material such as concrete and aluminum finished in a yellow and black tiger stripe pattern. An L-shaped cutout 2 is provided at one corner of the fence 1, and a self-luminous device 5 for lighting a light emitting diode 4 in a solar cell module 3 is fitted into the cutout 2.

The self-luminous device 5 is provided with a solar cell module 3 on its upper surface, and has a plurality of light-emitting diodes 4 arranged in an L shape on its front surface. As shown in FIG. 3, in the solar cell module 3, a storage battery 6, a switch 7, a lighting circuit 9 in which an electronic circuit 8 for controlling blinking of the light emitting diode 5 is connected in series, and an electromotive force of the solar cell module 3 A sensor circuit 10 having a relay that detects a predetermined voltage and closes the switch 7 when the voltage becomes lower than the predetermined voltage and opens the switch 7 when the voltage becomes higher than the predetermined voltage is connected.

The sensor circuit 10 detects a predetermined voltage of the electromotive force of the solar cell module 3, and the voltage is equal to or higher than the predetermined voltage while the sun rays are being radiated. During that time, the switch 7 is opened by a relay. The storage battery 6 is charged with the electromotive force of the solar cell module 3. In addition, the switch 7 is formed to be closed by a relay when the irradiation of the sun's rays weakens and becomes lower than a predetermined voltage.

The electronic circuit 8 may control a large number of the respective light emitting diodes 5 to be simultaneously blinked at regular intervals, or may be sequentially blinked from the outer side to the inner side of the railroad crossing or vice versa. It may be controlled.

While the sunlight is being irradiated, the storage battery 6 is charged with the electromotive force of the solar cell module 3. When the irradiation of the sunlight is weakened and the voltage falls below a predetermined voltage, the sensor circuit 10 turns on the lighting circuit 9. It starts up and supplies the electric power charged while it is being irradiated by the sun's rays from the storage battery 6 to the electronic circuit 8 so that the light emitting diode 4 blinks and lights up. Therefore, not only passersby but also the driver of the vehicle can take off from a distance. You will be able to confirm the position reliably.

[0012]

[Effect of device]

 If the railroad crossing caution fence according to the present invention is provided on both sides of the entrance and exit of the railroad crossing, since it uses a self-luminous device, it is easier to recognize than a retroreflector, and even a distant vehicle driver or pedestrian can see the light emitting diode. The presence of the railroad crossing can be surely recognized early by the bright light. Further, even if the interior of the railroad crossing is dark without being illuminated, the same effect as described above can be obtained and safety can be secured.
